Drying process refers to through each method, such as centrifugation, extruding, heating, drying, removes the mistake of moisture in object
Often there is large quantity of moisture in some wastes, in offal treatment process, generally require to be dried in journey, to mitigate
Waste weight reduces subsequent treatment cost.
When the drying process of many objects, because Environmental Factors cannot allow the exhaust gas after drying to be discharged into air, than
Such as sludge, excrement, the chemical products containing pernicious gas, general traditional drying means be adsorbed using desiccant to
Vapor in drying objects, but the method operating cost is high, drying cost is difficult for the sludge big for dry amount, excrement
To bear.
Summary of the invention

Closed self-loopa drying system of the invention, structurally reasonable, stable, operating cost is low, hothouse it is wet
Hot-air enters dehumidification system, and dehumidification system uses dynamic adsorption method i.e.: during the low temperature water droplet absorption dehydration of atomization
The vapor of generation, then by the temperature of cooling tower reduction cooling water, the air of atomization divides water droplet and air by centrifugal chamber
From obtaining Cryogenic air, Cryogenic air sends hothouse back to after entering air supply tube, is thusly-formed circulation, and whole process is not outwardly
Discharge exhaust gas.
Dehumidification principle, which is different temperature, different saturation of the air humidity, for example, at 70 DEG C saturated steam water content
For 196 grams/m3 air, it is 51 grams/m3 air that 40 DEG C, which are the water content of saturation of the air vapor, if we pass through water at low temperature spray
The air for drenching high temperature and humidity gives its cooling, then the water in the air of high temperature and humidity will be absorbed by low temperature water mist, air themperature
After reduction, water content is also reduced, and 70 DEG C of saturated moist air, which is reduced to 40 DEG C, will condense 196-51=145 gram water, that is to say, that
Every cubic metre of air can condense out 145 grams of water, and the water content in every cube of air is reduced to 51 grams, when these air are weighed
It newly is heated to become dry air again at 70 DEG C, can be used for evaporating the moisture of material.This spray process water is constantly risen
Temperature is just unfavorable for absorbing the water in damp-heat air after water temperature increases, and then we recycle after being cooled down with cooling tower water supply and make
With.
The key of this technology is not utilize the dry air of environment, also with regard to not having to environmental emission air frowzy,
Itself produces low-moisture air, is recycled.

Can all lead to the increases of equipment cost and operating cost a bit, but the thinking that provides of this technology for air filtering provide one very well
Direction.
Working principle:
The closed self-loopa drying system of the present invention, needs dry material to enter in hothouse 1 from feed inlet 11, wrong by left and right
The conveyer belt 7 set successively conveying downwards is opened up, power-assisted air duct 8 is set between adjacent transport layer 1a, is provided by power-assisted blower 8a
Power accelerate air flowing.The air (with the vapor generated in drying process in air) of hothouse enters dehumidifying system
System absorbs the vapor in air by the water droplet that atomizer 52 is atomized using dynamic adsorption method, and the water droplet of atomization can be right
The particulate matters such as the dust in air are adsorbed, are cleaned, and the air for being mingled with water droplet continues under the effect of negative pressure fan 32 along spray
It drenches the movement of channel 21 and enters in centrifugal chamber 22.
In centrifugal chamber 22, motor 41 drives the rotation of centrifugal impeller 4 and generates centrifugal force, be mingled with the air of water droplet from
Under mental power function, water droplet and air separation, water droplet are got rid of under the influence of centrifugal force to the inner wall of centrifugal chamber 22, flow into centrifugal chamber
22 bottoms finally flow into cooling tower 6 from water return pipeline 54 and are cooled down；And the air of water droplet then going out from centrifugal chamber 22 is separated
22b is discharged into air supply tube 3 at mouthful, is sent back in hothouse 1 after being heated in air supply tube 3 by heating device 31 for next round
It is dry.It is thusly-formed the self-loopa of air in system, whole process does not discharge exhaust gas outwardly.
Water of the water of the water injector 5 of dehumidification system in cooling tower 6, cooling tower 6 is under water pump 53a effect from sending
Waterpipe 53 is delivered to atomizer 52, after the water droplet absorption particulate matter that atomizer 52 sprays, returns after the centrifugation of centrifugal chamber 22
It is flow to cooling tower 6, result in formation of the circulations of water in system.
Highly preferred embodiment of the present invention has illustrated, and the various change or remodeling made by those of ordinary skill in the art are not
